It is a difficult process to check the correct operation of a thermal fan clutch.
Mostly if it is suspected the clutch is not working as it should and the age and the mileage of the car is significant it is best to replace the unit.
The clutch would be suspected if strange noises are heard that can be traced to the fan or if some engine overheating is being experienced, mostly at low speed or extended periods of idling.
To check the fan meets specification, first you need to know the temperature the clutch is designed to fully engage and then by whatever means available the fan clutch must be raised to that temperature and force applied to ensure direct drive has been achieved.
Testimonial: "Thank you for your reply, Vernon Taylor, you most likely saved me from an expensive miskake. It is definitely not my fan clutch, more likely my thermostat is stuck or no good. Thanks again."
